4,4-DISUBSTITUTED PIPERIDINE DERIVATIVES USEFUL AS FOUR-POINTED LIGANDS FOR COMPLEXING NUCLIDES IN NUCLEAR MEDICINE

摘要

Complexing agents for nuclides used in nuclear medicine are disclosed, as well as a process for preparing these complexes and diagnosing agents containing the complexes (I) and their complexes, in particular with Tc-99m. These compounds are used as non-invasive, functional in vivo diagnosing agents in nuclear medicine.
